Microsoft has been granted a stay of a landmark injunction in a patent infringement case that would have required the software giant to stop selling its popular Word in its current form by next month. The U.S. Court of Appeals for the Federal Circuit on Thursday granted Microsoft's motion for a stay, pending appeal, of an injunction issued in August by a federal judge that bars sales of Word that include a custom XML code found to infringe on patents held by i4i - the plaintiff.
